When I was younger in 2nd grade (1970'ish), I saw a film in class
narrated by Walter Cronkite that featured a mouse that breathed
underwater without any apparatus. The mouse reportedly had its lungs
filled with some miracle substance.
I want to download this footage. Can anyone help me?

From what I've found, I think the video is too old
to be on the internet. Additionally, it probably 
belonged to the network, and wouldn't be in the 
public domain. A picture and article about the
experiment is available on the BrokeKid blog, 
noting that the experiment took place in 1966:

Let me know if this satisfies your interests in
asking this question.

There is footage equivalent to this involving a rat in James Cameron's
"The Abyss" if that is of any use.

Here a picture of a mouse breathing in fluid

The mouse was breathing an oxygenated halogen liquid. A much more
viscous version is used to lubricate air compressors that fill scuba
tanks. From the search I did, information is hard to find on the
subject. The following is a citation of a study about the topic
